    摘要: A through hole is formed in an inner-side yoke making up a magnetic circuit portion, passing therethrough following a vibration direction of a vibration unit, and circuit boards are disposed in the through hole. The circuit boards are disposed with board surfaces thereof following the vibration direction of the vibration unit. Also, an opening area of a middle space across which the circuit boards oppose each other is larger than opening areas of side spaces. Accordingly, flow quantity of air through the through hole can be obtained, increase in air resistance at the time of vibration of the vibration unit can be suppressed, and also wind velocity can be obtained, whereby cooling effects of heat-generating components mounted on the circuit boards can be improved.

    摘要: A rear side of a vibration part of a speaker is covered by a cover member, and a duct is provided at the cover member. The cover member has a recessed portion, and an air flow path is formed inside the recessed portion. A circuit part is mounted on an outer surface of the cover member, and a heat sink provided in the air flow path is connected to the circuit part to allow heat conduction. Due to vibration of the vibration part, an airflow in the air flow path is accelerated and thus the effect of dissipating heat from the heat sink is increased.

    摘要: Bass reflex type loudspeaker enclosure comprising a cabinet, a loudspeaker and a first vent. The acoustic loudspeaker enclosure further comprises a second vent and an internal heat sink which is located inside the cabinet and intended to be thermally coupled to an electrical component in order to dissipate, inside the cabinet, heat produced by the electrical component, the first vent, the second vent and the internal heat sink being positioned so that an air flow which flows through the first vent, the second vent and into the cabinet moves the heat produced by the electrical component out of the cabinet.

    摘要: A speaker apparatus is provided in order to both receive and dissipate heat and to provide acoustic absorption for sound waves propagating through a speaker cavity. The speaker apparatus includes a speaker and a speaker cavity configured to receive sound waves emitted by the speaker for propagation through the speaker cavity. The speaker apparatus also includes a heat dissipation structure disposed at least partially within the speaker cavity. The heat dissipation structure includes a thermally conductive mesh that at least partially fills the speaker cavity. The heat dissipation structure further includes an active element configured to direct heat generated by a component into the thermally conductive mesh for dissipation therein. The thermally conductive mesh is configured to provide acoustic absorption for the sound waves propagating through the speaker cavity.

    摘要: A speaker includes a center pole, a voice coil, a diaphragm, and a turbulent flow generator. A center pole includes a through hole formed in the center pole in an axial direction. The voice coil is disposed around the center pole. A diaphragm includes a center cap that is disposed to face an opening of the through hole. A turbulent flow generator is disposed inside the through hole. The turbulent flow generator generates a turbulent flow inside the through hole.

    摘要: Acoustic transducer systems are described herein and in particular, acoustic transducer systems involving high displacement are described. An example acoustic transducer system includes an acoustic driver, a diaphragm position sensing module for generating a position signal corresponding to a displacement of a diaphragm of the acoustic driver, and a controller operable to: receive an input audio signal; generate a control signal based at least on the input audio signal and the position signal; and transmit the control signal to a voice coil operably coupled to the diaphragm so that the voice coil moves within an air gap within the acoustic driver at least partially in response to the control signal. A height of the voice coil can correspond substantially to a gap height in some embodiments.
